SYSTEM ERRORS
When the remote control is switched on, it may signal the presence of system errors.
Checksum error flash
If the error is detected, all the leds will flash quickly.
In this case an assistance point or the Quick
SYSTEM PROBLEMS
System problems are listed below, divided into two categories:
automatic reset problems and manual reset problems.
AUTOMATIC RESET PROBLEMS
Resetting after problems of this type occurs automatically, as soon as the cause that has generated the problem
disappears.
Low voltage supply
The signalling occurs only when the control is enabled.
The problem is signalled if the power supply voltage descends below 10.5Vdc for more than one second.
Resetting after this problem occurs if the power supply voltage exceeds the threshold of 11.5Vdc for more than
one second. Check the charge state of the battery group that supplies is derived or the electrical circuit.
In the presence of this problem the enablement LEDs slowly flash with a sound, when they are switched off.
Protection against prolonged motor activity
After activating the single thruster for about 5 minutes continuously, the relevant thruster command (of bow or
of stern) is interrupted.
The control is put in the disabled state with simultaneous flashing of the green and red led of the involved line
(bow or stern) and of the enablement leds, with a sound being emitted when they light.
This status is stored by the control. Its switching off, followed by its switching on, won't reset the problem.
The partial enablement of the remote control is allowed if the other propeller (of bow or of stern) is not involved
with the protection against prolonged motor activity.
Resetting after this problem occurs automatically after a period of time, calculated by the remote control, neces-
sary to partially cool the thruster.
MANUAL RESET PROBLEMS
The control will signal, with a certain number of flashes of the enablement LEDs, the presence of any manual
reset problems. Together with the flashes a short sound can be heard.
What follows is the correlation table between the flashes and the manual reset problems:

DESCRIPTION
The problem is signalled when the control detects a short circuit or an overload on the command
electrical line of the propeller. Check the wiring of the electrical line of the remote control to the
propeller and the absorption of the remote control switches installed on the propeller.
The problem is signalled when the control detects an interruption on the command electrical
line of the propeller.
Check the wiring of the electrical line of the remote control to the propeller.
The control system of the BTR propeller has detected a problem.
Refer to the BTR use and maintenance manual.
The control system of the PSS switch has detected a problem. Refer to the PSS use and
maintenance manual.
The TMS line switch has detected a problem connected to the remote control switch of the
propeller.
Refer to the TMS use and maintenance manual.
